Runs are teal for a selected line, or coloured by line in the network view. Red marks a currently off-reference section; amber is earlier evidence. Muted purple shows stale unresolved evidence only when enabled. Solid paths are fitted estimates; dashed paths and small dots are GPS. Unfitted links over 100 m stay disconnected. Stop changes are unverified. Paths end at the latest recorded position. Missing GPS stays disconnected; unobserved starts are marked partial.
